Awesome chapter! 5/5!!
It was surprising to see Sasuke once again! Plus, I'm glad that Gai and Kakashi aren't getting owned so quickly (or at least not yet). Seems like Kakashi is the 'brains', whereas Gai is the 'brawn' of their tag-team.
It's really interesting how the Nine Tails is developing, too.
Can't wait for Chapter 568! xd
By the way, doesn't Tobi's chain technique remind you of Kushina's ability? Did he use the Sharingan to copy the technique or is there something more sinister to Tobi?
